The change in political leaders sparks paranoia among American CIA officials, so CIA director Bill Cabot recruits a young analyst to supply insight and advice on the situation. Then the unthinkable happens: a nuclear bomb explodes in a U.S. city, and America is quick to blame the Russians. What they don't realize is terrorists, bent on provoking open war between the two nations, are behind it all.
